[PATCH v2 0/3] Add support for QSGMII mode for J721e CPSW9G to am65-cpsw driver

[PATCH v2 0/3] Add support for QSGMII mode for J721e CPSW9G to am65-cpsw driver

[Siddharth Vadapalli]

Add compatible to am65-cpsw driver for J721e CPSW9G, which contains 8
external ports and 1 internal host port.

Add support to power on and power off the SERDES PHY which is used by the
CPSW MAC.

=========
Changelog
=========
v1 -> v2:
1. Drop all patches corresponding to SGMII mode. This is done since I do
   not have a method to test SGMII in the standard mode which uses an
   SGMII PHY. The previous series used SGMII in a fixed-link mode,
   bypassing the SGMII PHY. I will post the SGMII patches in a future
   series after testing them.
2. Drop all patches corresponding to fixed-link in the am65-cpsw driver.
   This is done since PHYLINK takes care of fixed-link automatically and
   there is no need to deal with fixed-link in a custom fashion.
3. Fix indentation errors in k3-am65-cpsw-nuss.yaml.
4. Remove the stale code which tries to power on and power off the CPSW
   MAC's phy, since the CPSW MAC's phy driver does not support it.
5. Rename the function "am65_cpsw_init_phy()" to
   "am65_cpsw_init_serdes_phy()", to indicate that the phy corresponds to
   the SERDES.
6. Invoke "am65_cpsw_disable_serdes_phy()" as a part of the cleanup that
   is associated with the "am65_cpsw_nuss_remove()" function.

[PATCH v2 1/3] dt-bindings: net: ti: k3-am654-cpsw-nuss: Update bindings for J721e CPSW9G

[Siddharth Vadapalli]

Update bindings for TI K3 J721e SoC which contains 9 ports (8 external
ports) CPSW9G module and add compatible for it.

Changes made:
    - Add new compatible ti,j721e-cpswxg-nuss for CPSW9G.
    - Extend pattern properties for new compatible.
    - Change maximum number of CPSW ports to 8 for new compatible.

[PATCH v2 3/3] net: ethernet: ti: am65-cpsw: Add support for SERDES configuration

Define the functions am65_cpsw_disable_phy(), am65_cpsw_enable_phy(),
am65_cpsw_disable_serdes_phy() and am65_cpsw_init_serdes_phy().

Power on and initialize the SerDes PHY in am65_cpsw_nuss_init_slave_ports()
by invoking am65_cpsw_init_serdes_phy().

Power off the SerDes PHY in am65_cpsw_nuss_remove() by invoking

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

I will fix the errors in the v3 series and ensure that there are no
errors or warnings with dt_binding_check, using the updated dt-schema
and yamllint.
